Summary
This study presents a high-quality gorilla genome assembly using advanced sequencing technology. The improved assembly offers significant insights into gorilla genetic diversity and structural variations.
Area of Science:
- Genomics
- Bioinformatics
- Evolutionary Biology
Background:
- Accurate genome sequencing and assembly are fundamental for understanding genetic variation.
- Previous gorilla genome assemblies had limitations in contiguity and gene model completeness.
Purpose of the Study:
- To generate a high-quality, contiguous assembly of the gorilla genome.
- To improve the understanding of genetic diversity, structural variation, and gene content in gorillas.
Main Methods:
- Utilized single-molecule, real-time (SMRT) sequencing technology.
- Employed a string graph de novo assembly algorithm for genome construction.
Main Results:
- Achieved a two to three orders of magnitude improvement in contiguity compared to previous assemblies.
- Recovered 87% of missing reference exons and incomplete gene models.
- Identified new biological insights into genetic diversity, structural variation, gene loss, and repeat structures.
Conclusions:
- The new gorilla genome assembly significantly enhances genomic research capabilities.
- This approach sets a precedent for routine, high-quality mammalian genome assembly, approaching human genome standards.

03:36Genome Annotation and Assembly
21.4K
The genome refers to all of the genetic material in an organism. It can range from a few million base pairs in microbial cells to several billion base pairs in many eukaryotic organisms. Genome assembly refers to the process of taking the DNA sequencing data and putting it all back together in a correct order to create a close representation of the original genome. This is followed by the identification of functional elements on the newly assembled genome, a process called genome annotation.

100.8K
The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.

02:54Evolutionary Relationships through Genome Comparisons
7.2K
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

In the same year as the discovery of the Sanger sequencing method, another group of scientists, Allan Maxam and Walter Gilbert, demonstrated their chemical-cleavage method for DNA sequencing. The Maxam-Gilbert method relies on using different chemicals that can cleave the DNA sequence at specific sites, the separation of resulting DNA fragments of variable size using electrophoresis, and deciphering the DNA sequence from the resulting gel bands.

Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.
